In the UK, the police seem to have little trouble being violent without guns. I think it's the threat of that kind of violence that they use to e.g. jail people. Some police officers do have guns, but they're a minority (and many of them in London refused to wield guns this week, in protest about a murder charge for a firearms officer who killed an unarmed man). As far as I can tell, non-police violence here also mostly doesn't involve guns. Knife crime seems to be more widespread.
